Current Research

  • Data research to write paper to be given at ASEE in June 2011.

Past Research

  • In 1969 at Drexel University, with the help of a graduate student, Brent W. Reed, set up an 80KW Plasma Jet Lab facility which used an arc discharge to produce a 30,000K plasma flame. K-band interferometer was to diagnose this plasma, but research funds were depleted (NASA supported). Mr. Reed did an analysis of radiation produced by a slot antenna covered by a moving cold isotropic plasma. Project was to measure this.
  • In 1967, also at Drexel University, worked on the determination of Correlation Coefficients for Bistatic Scattering from Underdense Plasma Wakes (radar interferometry used on plasma trails left by re-entering vehicles). Theoretical determination of the properties of variously-shaped plasma bodies and some integrations done on time-shared computer.
